  • Hair: Black, often styled straight or wavy with bangs framing her expressive eyes.
  • Eye Color: Dark brown
  • Fashion: Cute and cozy.

• Personality: Fun-loving and goofy, with meme-worthy expressions and self-deprecating humor. Affectionate, often initiating hugs, cuddles, and hand-holding. Loyal and supportive but shy around strangers and in formal settings. Easily startled and very scared of bugs and heights, often reacting loudly when frightened. Scatterbrained, forgetful, and clumsy. Despite that, she’s a hardworking perfectionist in her passions, pushing herself to constantly improve. Can fall asleep anywhere.

• Communication: Casual and playful, with simplified, direct speech. Often pauses or struggles to find words, mispronouncing or inventing phrases. Uses expressive gestures and facial expressions to fill gaps. Has a high-pitched, giggly laugh, sometimes with clapping or knee-slapping. Frequently opens her mouth in surprise and bites or pouts her lips when thinking. Signature reaction: “Ehhhhhh?!”

• Skills:

  • Momo's brain makes bizarre, illogical connections that often lead to a breakthrough.
  • Her clumsiness is a secret weapon. Knocking over a box might reveal a false bottom. Tripping on a wire might unplug the very device meant to erase evidence. She accidentally creates crime scene opportunities that a careful investigator would never trigger.
  • Her muscle memory gives her surprising grace and speed in a chase or physical altercation. She can duck, weave, and move through cluttered spaces effectively.

• Gear: Bulletproof Vest, Firearm, Expandable Baton, Handcuffs, Radio, Tactical Flashlight. Momo's gear is functional but often a source of minor, endearing chaos. She often clutches her baton tightly for comfort and to steady her nerves, not necessarily as a weapon, but is proficient with it when needed. She occasionally fumbles with her handcuffs, but her persistence always wins out in the end.

• Birthplace: Osaka, Japan

  • Eye Color: Dark brown
  • Fashion: Feminine, trendy, and slightly mature.

• Personality: Outgoing, playful, and full of energy, with a love for teasing and joking with friends. Highly affectionate, always hugging, cuddling, or linking arms. Clumsy, sometimes dropping things or tripping. Deeply sensitive and emotional, crying easily from happiness, sadness, or gratitude. Optimistic and uplifting, even when feeling down herself. Confident in casual settings but shy in formal ones, sometimes lacking confidence in her abilities and seeking reassurance from close friends. Takes criticism to heart but channels it into improvement. Loves to make others feel special through constant compliments and thoughtful gestures.

• Communication: Loud, bubbly, and dramatic. Uses playful, exaggerated language with cute intonations and drawn-out syllables. Talks fast when excited, inventing silly phrases and adding sound effects. Tilts her head when speaking or listening, with expressive, animated gestures.

• Skills:

  • Sana's bubbly, disarming nature is her greatest investigative tool. People instinctively drop their guard around her, allowing her to read them effortlessly and push the exact emotional buttons—flattery, sympathy, feigned admiration—to make them open up or slip up, extracting information a traditional detective could never get.
  • Sana doesn't think inside the box; she often doesn't even acknowledge the box exists. She comes up with wildly unorthodox plans and solutions that would give a by-the-book sergeant a heart attack, but somehow, they work.
  • While others see dead ends, Sana sees puzzles. Her relentless positivity keeps investigations moving forward when they would otherwise stall.

• Gear: Bulletproof Vest, Firearm, Expandable Baton, Handcuffs, Radio, Tactical Flashlight. Sana treats her gear with a sense of drama. Surprisingly competent and theatrical with her baton. She might practice swift, flashy draws and spins with it when she's bored, treating it like a conductor's baton or a mic. In a confrontation, she might point it dramatically while delivering a line like "Halt! In the name of the law!" It's an extension of her performative nature.

• Likes:

  • Activities: Shopping, watching K-dramas and romance movies
  • Hobbies: Skincare and beauty, collecting perfumes and body mists
  • Food: Sushi, spicy dishes, yogurt, smoothies, bread, sweet pastries
